Supertech has been around for a long time in the Valvetrain industry, and has race proven their product year after year, and backed it up with world records and first place trophies. We use Supertech in our top level engine builds for good reason. We suggest Supertech Valvesprings and Retainers and actually use them in some of our very own cars.

There are 3 Major Issues with stock valvetrain, that can be prevented by using Supertech Components.

  • Valve Float - When we rev our engines higher than they were designed to rev from the factory (which we often do when racing), sometimes the factory springs may not be strong enough to fully pop all the way back up and close the valve between rotations of the cam. This makes the valve actually stay open during the combustion stage of the engine cycle, leaking compression out of the engine, and losing power under load.

  • Coil Bind and Valvespring Failure - Factory valvesprings are made from cost effective materials that will survive normal driving, usually the entire life span of a un-modified car. The factory did not account for enthusiasts when they chose materials which is why it is common for high mileage factory valvesprings to crack or break when put through the abuse of racing. High RPM, increased compression, aggressive cam profiles, and other factors can cause valvesprings to perminantly bend out of shape (coil bind) or even break and drop into the engine (spring failure), potentially causing irrepairable damage. Supertech's valvesprings are made from carefully chosen alloys to stand up to the worst abuse.

Readable
Format: Hardcover, Format: Hardcover
Not at all what I would consider “Very Good” condition, as the book was described. Pretty disappointed to be honest, considering I paid over $100 for this. It’s beaten up, torn, and dirty, but it’s readable.

Not as listed!
Format: Hardcover
I paid nearly 300 dollars for this book and it was not as listed. I bought this because it was listed as new, but the book arrived with a broken binding, highlighting and writing throughout the pages, and the course ecode was already used. Unfortunately, I cannot use it for my studies.

Coverage lined up nearly perfectly with my fed courts class
Format: Paperback
Almost every case we covered in class and definitely every concept is covered, and explained helpfully, in this E&E. The problems are helpful, too.

Great Federal Courts supplement
Format: Paperback
This E&E book really helped with Fed. Courts! Incorporate the public v. private law models/SOP and federalist v. nationalist paradigms which my professor used in the course. This version doesn't have some of the newer cases (TransUnion v. Ramirez). The standing section could have more info but standing is one of the easiest doctrines in fed courts. The Habeas Corpus, particularly the Teague Doctrine and AEDPA, section is excellent. The only big thing this book does not include are universal injunctions and the scope of remedies (outside of standing, anti-injunction act, and section 1983).
